Many engineering applications involving piping systems utilize flow passage restrictions such as control valves and orifices to achieve control of flow rates and pressures. Accurate determination of flow characteristics through these restrictions especially orifices is important for industrial operations such as control measures in HVAC, quality control in food processing industry, metering of high viscous liquids and calibrating tools in metrology of liquid and gas flows.
This paper gives a review on the numerical analysis of different slotted orifice plate used for flow measurement of liquids.
